Frequently Asked Questions
What is a vignette effect?
A vignette is a gradual darkening of the edges of an image, drawing the viewer's eye toward the center. It's a classic photography technique used since the earliest days of film.
Can I control how strong the vignette is?
Yes. Intensity runs from 10% to 100%, while size runs from 20% to 100%; both start at 60%. The tool draws a centered radial black overlay whose inner radius follows the size setting and whose edge opacity follows intensity. Inspect off-center subjects and corners before downloading.
Which input and output formats are used?
The tool accepts JPEG, PNG, and WebP and keeps that output family. PNG uses lossless coding for the rendered raster; JPEG and WebP are re-encoded at a requested quality of 0.92. Metadata, profiles, exact values, and hidden alpha data can change.
